Description
The AX53 is a heavy-duty classical cogged (notched) V-belt featuring a 1/2-inch top width, a 5/16-inch thickness, and a 55-inch outside circumference. The molded cogs on the inner surface allow the belt to bend easily around exceptionally small-diameter pulleys while significantly reducing heat buildup and flex fatigue.
Key Specifications
- Belt Series: AX Cross-Section
- Top Width: 1/2 in (13 mm)
- Thickness / Height: 5/16 in (8 mm)
- Inside Length (Pitch): 53 in (1346 mm)
- Outside Length: 55 in (1397 mm)
- Construction: Raw-edge, single-band cogged
Materials & Performance
- Tensile Cords: High-strength, low-stretch polyester cords designed for equal load distribution and shock absorption.
- Body Compound: Fiber-loaded EPDM or chloroprene rubber compound engineered to maximize sidewall rigidity and stability.
- Raw-Edge Sidewalls: Unwrapped sides offer a high-friction grip against pulley grooves, providing higher horsepower ratings and lower slippage than standard wrapped belts.
- Environmental Resistance: Built to meet RMA standards for heat resistance, oil resistance, and static conductivity.
Common Uses
- Commercial HVAC air handlers, exhaust blowers, and large fans
- Heavy industrial machinery, pumps, and air compressors
- Agricultural equipment, including conveyors and grain-handling systems
